WebpackNetteAdapter is a tool that helps integrate your Nette Framework application with assets built via Webpack.

Installation and requirements

$ composer require oops/webpack-nette-adapter

Oops/WebpackNetteAdapter requires PHP >= 7.1.


Register the extension in your config file, and configure it. The two build options are mandatory:

    webpack: Oops\WebpackNetteAdapter\DI\WebpackExtension(%debugMode%)

        directory: %wwwDir%/dist
        publicPath: dist/

Now you can use the {webpack} macro in your templates. It automatically expands the provided asset name to the full path as configured:

<script src="{webpack app.js}"></script>

webpack-dev-server integration

You might want to use the Webpack's dev server to facilitate the development of client-side assets. But maybe once you're done with the client-side, you would like to build the back-end without having to start up the dev server.

WebpackNetteAdapter effectively solves this problem: it automatically serves assets from the dev server if available (i.e. it responds within a specified timeout), and falls back to the build directory otherwise. All you have to do is configure the dev server URL. The dev server is enabled automatically in debug mode; you can override this setting via enabled option:

        enabled: %debugMode% # default
        url: http://localhost:3000
        timeout: 0.1 # (seconds) default

Asset resolvers and manifest file

You might want to include the Webpack's asset hash in its file name for assets caching (and automatic cache busting in new releases) in the user agent. But how do you reference the asset files in your code if their names are dynamic?

WebpackNetteAdapter comes to the rescue. You can employ the webpack-manifest-plugin or some similar plugin to produce a manifest file, and then configure the adapter to use it:

        name: manifest.json

This way, you can keep using the original asset names, and they get expanded automatically following the resolutions from the manifest file.

WebpackNetteAdapter automatically optimizes this in production environment by loading the manifest file in compile time.


In development environment, WebpackNetteAdapter registers its own debug bar panel into Tracy, giving you the overview of

  • what assets have been resolved and how;
  • the path from where the assets are served;
  • whether the dev server is enabled and available.

Debug bar panel

  • 1.1.0 1.1.0

    • This release brings compatibility with Nette 3.0 🎉 (as well as Nette 2.4 at the same time). Also, PHP version requirement has been raised to 7.1.
    • Some hidden hard dependencies on Nette packages (such as nette/application or nette/http) have been removed, so that WebpackNetteAdapter can be employed even in less traditional development stacks.
    • The timeout of DevServer's heartbeat check is now configurable, defaulting to the current value of 100 ms.
